问题
While running my app on iPhone, I needed to view the database contents. So I selected Devices in Xcode and chose my device. Thereafter, I selected my app and clicked on the Settings button which shows 3 options: Show container, Download container and Remove container. On clicking the Download container option, I was asked where I want to store the container. After selecting the location, I am getting the following error: An error occured while attempting to download the container from application "MyApp".....
On selecting Show container option, a list opens up but there is no file inside it.
The same problem occurs with other apps too that I run using Xcode.
Any ideas as to why this happens and how to fix it?

Restarting the device in question worked for me. Hope it helps!
